TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No. 639,297, dated December19, 1899.

Application filed January 27, 1898. Serial No. 668,167. (No model.) i

To ctZZ whom it may concern:

Be it known that I, WILLIAM M. RUSSELL, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Temporary Binders, of which thefollowing is a specification.

This invention relates to improvements in temporary binders of thatclass wherein the sheets or leaves to be bound or held in place aresecured between two main lids or covers by being perforated or notchedand placed over rods or posts that extend from one cover to the otherand which are usually permanently secured to the bottom or back coverand project through holes in the front or upper cover. The commonobjection to binders of this class is that the rods (or posts, as theyare called in the trade) connecting the two covers being made severalinches long in order to accommodate a large number of leaves projectconsiderably above the upper cover and make the whole binder unsightlyandinconvenient whenitisbutpartiallyfilled.

The object of this invention is to provide a means for avoiding theselong protruding posts in a but partly filled binder; and the inventionresides in the novel feature of construction set forth in the followingspecification and claims and illustrated in the annexed drawings, inwhich- Figure 1 shows a general view of the post embodying my invention.Fig. 2 shows a ver tical section through the center of oneinterchangeable section of the post. Fig. 3 shows a binder having postsof my improved construction. Fig. 4 shows a general view of theornamental ball-cap as separate from the rest of the post, and Fig. 5shows a means employed to lock the top cover to the post.

My post consists of a short lower section A, which is fastened rigidlyto the lower cover of the binder by means of a threaded end A or by anyother suitable means and provided at its upper end with means,preferably female threads, for connection with other short sections, andof a series of short interchangeable sections 13 B, &c., joined togetherand to such lower section by the interlocking of male and female threadswith which said sections are fitted, and of a ba1l-cap 0., provided withmale threads to connect with the top most section of the post. All ofthe sections excepting the ball-cap are of the same diam= eter and formand when fitted tightly together form in efiect and appearance a longand solid post. The ball-cap I prefer to make larger in diameter thanthe other sections, which adds to its ornamentation.

Fig. 2 is a vertical section through the center of one interchangeablesection of the post, showing the construction of the male threads F andthe female threads E. The milling of the male and female threads leavesbearing faces E and F at the point of closest contact on each section,which bearing-faces aid to give the post great rigidity when thesections are screwed tightly together.

Fig. 3 shows the application of the post to the binder itself. The firstor lower section A is fitted at its lower end with any means forfastening it rigidly to the lower cover G of the binder, preferablythreads A, as shown in Fig. l. The upper end of such lower section isfitted with female threads to fit the male threads of the next sectionabove. The upper cover G is provided with apertures corresponding tosaid post or posts fitted to the lower cover G u )on which osts b meansof such apertures, the top cover G is arranged to slide. The said lowersection A may of course be so arranged as to be interchangeable with theother sections of the post by fitting it with male threads below tocorrespond with the female threads above and fitting said male threadsinto corresponding female threads in the lower cover G, the bearing-faceon said section formed by the cutting of such male threads giving theconnection added rigidity.

The sections of the post other than the lower one just described consistof shortsections of the same shape and diameter as the lower section Aand fitted each with female threads E at one end and with male threads Fat the each section is provided with a small hole D, drilleddiametrically through the section, whereby by the insertion of somestiff pin or bar into said hole the sections may be screwed tightlytogether or easily loosened when so tightly screwed. In order to gain afurther advantage from this hole D, I prefer to have it pass through thesection immediately at the end' of the female threads E and be connectedtherewith, thereby providinga means for the escape of dust or othersuchacc um ulations in such female threads through such hole out at thesides of the section.

The bearing-faces E and F on the ends of each section are formed by thethreading and aid to make rigid the post formed by the sections screwedtightly together.

The ball-cap 0, Fig. 4, provided with male threads to screw into theuppermost section of the post, serves as an ornament and prevents theends of the post from scratching the furniture, and also serves to keepdust from the female threads of the top section. This cap may be made ofany desirable size, shape, or material.

The sections of my post may be made of any hard metal or other materialand may be round, triangular, or of any desirable form and of anydesirable size, threaded as shown or reversely. While I prefer toconnect said sections by means of threads, any other desirable means offorming said connections may be used, provided said means lies-withinthe external wall of the post, and thus does not interfere with itsuniformity of diameter or external smoothness.

The locking mechanism shown in Fig.5 is the same as that illustrated inPatent No. 448,411, of March 17, 1891, to Copeland and Ohatterson (seeFig. 2 of said patent) and is what has been used for the purpose; butany other suitable locking mechanism desired may be used, or even thefriction between the parts may be found sufficient for some purposes.Said locking device consists of the hollow bar or casing J, having thesliding bar J therein. Said sliding bar J is formed of a solid end 7'and two side pieces (1, braced and supported by a cross-bar q. Betweensaid side pieces are sliding blocks K and K. Said block-K is formed withan oblong perforation with a sharp internal edge and is placed over onepost, and the block K has a semicircular notch in its end, mounted closeto and adapted to engage with the other post. Just behind the block Kinternal lugs q' are formed on the side pieces, and similar lugs g justbehind the block K. A spring 0, interposed between the cross-bar q andthe block K, normally tends to force it toward the end 9'', and a spring0, connecting the block K to the opposite end of the casing J, normallytends to draw said block back and away from the adjacent post. A screw Zextends through a screw-threaded perforation in the solid end r to bearagainst the end of block K. A ring Z is secured thereon just behind aninternal flange m on the block or plug in the end of easing J. To lookthe device to the posts, the screw is turned to force the block K inwarduntil it bears against the post adjacent thereto, which it engages withits sharp edge, and at the same time the bar J will be drawn forwardwith the block K until it engages its post. By reversing the operationthe parts are allowed to be forced away from the posts by the action ofthe springs 0 and 0, all of which will be readily understood by aninspection of said Fig. 5.

- I do not wish to be understood as limiting my invention to the use ofany particular locking or clamping mechanism whereby the upper cover orany clamping device employed for holding the perforated sheets togetheris held in position on the posts, as it is obvious that the particularform of sectional posts employed maybe used irrespective of theconstruction of the upper cover or clamping device.

Having thus fully described my said in vention, what I claim as new, anddesire to secure by Letters Patent, is

1. In abinder, the combination with the cover-sections, of a post orposts secured to one of said cover-sections and projecting therefrom,each post consisting of a plurality of parts joined byinteriorly-locking sockets and stems with bearing-faces formed aroundsaid interlocking parts at the joints, which bear against each other,whereby said post is made rigid, said post or posts being adapted topass through openings in leaves inserted between said cover-sections,and through openings in one of said cover-sections, substantially as setforth.

2. The combination, in a temporary binder, of a lower cover, posts orrods rigidly fastened thereto, an upper cover perforated and mountedtoslide on said posts or rods, each of said post-s consisting ofinterchangeable sections, which when fitted together provide apost whoseexposed portion is of uniform external diameter, means for rigidlyconnecting and disconnecting said sections, and means for locking saidupper cover in the adjusted position on said posts, substantially as setforth.

3: The combination with temporary binders consisting of two coversconnected by posts or rods rigidly fastened to the lower cover and uponwhich posts the upper cover slides by means of apertures fitting uponsaid posts, said posts consisting of short lower sections rigidlyscrewed into the lower cover and fitted with female threads at theirupper ends, and of other and interchangeable sections fitted with maleand female threads as means of readily connecting and disconnecting suchsections, with bearing-faces on either end at the point of closestconnection, each section being provided with a small hole drilleddiametrically through the section, and an ornamental ball-cap providedwith male threads to connect with the female threads of the topmostsection, substantially as shown and described and for the purposesspecified.

4. Inabinder, the combination, with coversections, of a post or postssecured to one of said cover-sections and projecting therefrom, eachpost consisting of a plurality of parts, one of said parts being securedto a coversection and having an interiorly-threaded socket or bore, andthe other part provided with a projecting stem of less diameter than themain portion of said part, said stem adapted to engage the threadedsocket of the other part, and the shoulder formed at the upper end ofthe threaded stem adapted to be brought into engagement with the upperend of the other part of the post, said post or posts adapted topassthrough openings in leaves inserted between the cover-sections betweenthe top and bottom members, sub- 35 stantially as set forth.
